Antoinette. Dayana. . 2B. The endocrine system. The . Endocrine system is made out of 8 major glands, they’re group of cells that produce and secrete chemicals. Organs such as the kidney, liver, heart and the gonads help the Endocrine System. The kidney secretes hormones (erythropoietin and renin).. Endocrine System.

Influences growth, metabolism, and homeostasis over prolonged periods. Secretes hormone products into interstitial spaces which are then absorbed into the blood and transported throughout the body. Hormonal control is much slower than nervous control, but the effects of the endocrine system are much longer lasting. Erin Pein, RN-BSN. What is Adrenal Insufficiency?. AI is a medical condition in which the adrenal glands cannot produce glucocorticoid hormone Cortisol. Cortisol is needed for the body to maintain normal energy supply, fluid and electrolyte balance, blood pressure, blood sugar and the body’s reaction to physical stress such as illness or injury.. for . communicating, controlling and . coordinating . the body’s work.
